4 Application filed January 23. 1895. Serial No. 535,953. (No model.)

To all whom it may concern.-

Be it known that we, FOLKERT KAEMPEN, Jr., and WILLIAM WEwERs, citizens of the United States, residing at Quincy, in lthe county of Adams and State ofY Illinois, have invented new and useful Improvements in Ovens for Cook Stoves or Ranges, of which the following is a specification.

Our invention relates to an improved oven for cook stoves and ranges, and has for its object to provide an oven so constructed that its component parts may be readily detached and replaced without detaching or removing any portion `of the outer easing of the stove, thus rendering the repair of the oven both inexpensive and easy, and has for a further object to facilitate the assembling together of the parts in the factory.

To these ends our inventionconsists in the novel features and the arrangement andcombination of parts hereinafter fully described and denitely pointed out in the claims following the description, due reference being had tothe accompanying drawings, forming a part of this specification, wherein- Figure 1 is a longitudinal sectional view of a stove, illustrating our improved oven in place. Fig. 2 is a transverse section thereof. Fig. 3 is a detail section taken on the line 3 3 of Fig. 2. Fig. 4 is a similar view taken on the line 4 4 of Fig. 1. Figs. 5, 6, 7, 8, and 9 are perspective views, respectively, of the top and front oven-plates, the fireback, and the` back and bottom oven'plates. Fig. 10 is a top plan view illustrating the top oven-plate in dottedlines. Fig. 11 is an end elevation illus trating the Iirebackin place. f

Referring to the drawings the numeral l indicates the base of a cook stove; 2, the top thereof; 3, the rear end; 4, a portion of the fire chamber; 5, the front side of the stove casing, and 6 the rear, and on a range the back or blind side, said parts constituting the outer casing, and which may be constructed and secured together in any desired or usual manner.

The front, back, top and bottom, of our improved oven consist of separate, detachable, plates that are adapted to be inserted in place within the stove casing and when properly placed in position serve to mutually support each other and rigidly hold each part against accidental displacement. The bottom of the oven is formed of two plates 7 and 8, each' of which is provided at its outer edge with a downwardly depending curved flange 9, and said plates at their meeting edges are provided with alternating straight portions lO and flanges -11, the latter being similar in all respects to the flanges 9 above referred to. The curved flanges 9 are adapted to rest beneath inwardly projecting flanges l2 formed upon the opposite sides of the base 1 'of the stove casing, the flanged and straight edges of the plates 8 and 9 interlocking with each other, and said plates resting upon the upper edges of the usual due strips 13 that are supported on the base of the stove. The front end, or the end next adjoining the lire chamber, of each of the bottom plates 7 and 8 rests upon a bead or cleat 3Sa cast upon the inner side of the frontplate 3S, and one of said plates, as 8, is provided with a bifurcated lug 14 adapted to be engaged by a fastening bolt passed through the front plate of the oven, and the rear or opposite ends of said bottom plates are provided with upt-urned flanges 15, which, together with lugs 16 cast on the upper side of said plates adjacent to said anges, serve to support the bottom ofthe back plate 17 of the oven. Said back plate 17 is cast in one dat piece and is provided at its upper and lower edges with inwardly and oppositely projecting flanges 1S and 19, the flanges 19 fitting between the fianges 15 and lug 16 of the bottom oven plates by which the back plate 17 is supported at its bottom against lateral displacement. Said back plate upon its opposite edges, and approximately midway between its top and bottom, is provided with pockets or recesses20 from whichto the extreme edges of the said plate extends a slot 21, the front and rear frames ot' the stove casing at points opposite said slots being provided with bolt holes 22 in which are inserted threaded bolts '23, the

ythreadedends of which pass through the slots ICO the stove casing. The top oven plate 25 is provided upon its opposite sides with outwardly and upwardly projecting flanges 26 and 27 which rest upon inwardly projecting flanges 28 formed on the under side of the top 2 of the stove casing and beneath lugs 29 also formed on said' top at suitable and uniform intervals apart, the rear edge of the plate 25 being provided at corresponding intervals with notches 30 which permits said plate being dropped over the lugs 29 to its seat on the flange 2b'. The rear end of the plate 25 is provided with a downwardly depending flange 31 that overhangs the flange 18 formed on the upper edge of the back plate 17. Said flange 18, at about its center, is provided with a bifurcated lug 32 and the top plate 25 with a corresponding bolt hole 33, a bolt 34 being passed through said bolt hole and flange and secured therein by a nut 35, by which means the top and back plates are firmly secured together. The front edge, or the edge adjoining the lire back, is formed with a downwardly curved and depending flange 36 which tits underthe upper edge of the fire back and said flange is provided with a bifurcated lug 37 that is engaged by a bolt passing through the fireback, as willhereinafterbe described. The front oven plate 38, at its lower edge, rests upon the base 1 of the stove casing and is held against lateral displacement by lugs 39 and 40 formed respectively on the said base andthe front and rear frames of the stove casing, said front plate and the bottom oven plates 7 and 8 being secured together by a bolt 41 passed through a suitable bolt hole formed in the front plate and through the bifurcated lug 14 before described. The upper edge of the front plate 38 is provided with a vertical offset flange 42 that is adapted to fit under and behind the lower edge of the re back, and is provided with a bifurcated lug 43 by means of which and a fastening bolt 44 said plate and fire back are secured together. The fire back 45 is formed at its upper edge with an inwardly projecting flange 46 that rests over the depending flange 36 of the top oven plate 25, and is secured thereto by a bolt 47 passed through a suitable bolt hole formed in the flange 46 and held in engagement with the lug 37 of the top plate by a nut 48.

In order to prevent lateral displacement of the fire back before, the bolts 44 and 47 are fastened in place or after they have been removed, the front and rear stove frames are provided with inwardly projecting lugs 49 that project beyond the outer edges of the tire back, and said fire back is provided upon one edge with a notch 50 that is adapted to register with the adjacent lug 49 when the end of the fire back is slightly raised to permit ofthe removal of the latter from behind the lug.

In assembling together the parts of the stove and our improved oven, the stove base is first put down, and the sides, back, front and top of the outer casing or body of the stove proper are placed in position and fastened together by tie bolts or similar fastenings commonly employed for the purpose. After the body of the stove has thus been erected the oven plates are put in place and fastened in the manner and by the means above described.

If any one of the oven plates should become broken, cracked, or otherwise injured, from any cause, the same may be removed with ease and dispatch without the necessity of removing, unfastening, or otherwise disturbing any of the parts of the stove body or casing, the plates being removed in the manner which we will now proceed to describe.

The fire back 45 is removed by unfastening the bolts 44 and 47 which respectively fasten it to the front and top oven plates and then lifting it out through the firechamber. To remove the back oven plate, the bolt 34 which secures said plate and the top plate 25 is first unfastened, the bolts 23 which secure it to the front and rear stove frames are next unfastened, and then by inclining the upper edge of the back plate inward the same may be removed through the oven door. The top oven plate 25 may be removed by first removing the fire back and back oven plate in the manner above described. The top oven plate is then moved forward toward the fire chamber until the notches 30 register with the lugs 29 on the the stove casing after which the notched side of said top oven plate is raised and the opposite side thereof slipped from between the flanges 2S and lugs 29 and the plate is lowered and taken out through the oven door.

To remove the bottom oven plates 7 and S the back oven plate is first taken out as before described, and the bolt 41 which fastens the bottom plates to the front plate is unfastened, after which the meeting edges of the bottom plates are raised, thus withdrawing their opposite outer edges from beneath the flange 12 of the side casing and the plates are then removed through the oven door.

Finally, to remove the front oven plate 3S, the fire back, and the back and bottom oven plates are taken out in the manner heretofore explained and the front oven plates may then be taken out through the top of the stove.

It will thus be seen that each or all of the oven plates may be removed and replaced without distributing any of the parts forming the stove body proper in any manner whatever, enabling the oven to be repaired with ease and dispatch and consequently with but slight expense, and also effecting a like economy of labor in assembling the parts together at the factory.

As above described, it will be apparent that the plates constituting the oven are tied in place by the back oven plate but it will be readily manifest to one skilled in the art that the same result may be accomplished by constituting one or more of the other plates the tie plate. It will also be readily understood IOO ISO

plate-and lire back detachably connected tothat instead of the fastening bolts shown and described other means for securing the oven plates together may be employed without departing from the spirit of' our invention.

We have shown the oven provided with a front and a rear door, but it will also be un-V derstood that one door only may be provided in the usual manner.

Ve have shown and described our improved oven as applied to a cook stove, but the same may with equal facility be applied to ranges, and by the term cook stoves we wish to be understood as including` either a cook stove in the conventional meaning of the term or a range.
